ABSTRACT:
An apparatus for sealing the tail of a wound roll of sheet material. A pair of parallel rotatable rollers define a tail separation station and a tail wind-up station that are disposed longitudinally along the length of the rollers A wound roll is positioned at the tail separating station and rotated about its axis. Air jets mounted adjacent the rollers separate the tail from the body of the roll, and the separated tail is supported on an apron that extends laterally from the rollers. After separation of the tail, rotation of the rollers is stopped and the roll with the separated tail is moved longitudinally along the rollers to the wind-up station. A strip of adhesive is applied to the tail from a fixed adhesive head as the tail is moved to the wind-up station. At the wind-up station the roll is rotated to wind the separated tail back onto the body of the roll.
